Abstract
To evaluate how CRC screening practices differ between e-cigarette users and non-users. Cross-sectional study design. National Cancer Institute's Health Information National Trends Survey (HINTS 5). Respondents aged 45 to 75years. Demographics, CRC screening, e-cigarette use, cancer history, presence of comorbidities, and access to a primary care provider. The demographic characteristics of the study participants were evaluated by their e-cigarette smoking status using chi-squared tests. The differences in CRC screening between e-cigarette users and non-users were evaluated using a multivariate logistic regression model. We identified a total of 6963 participants, of which 181 (2.6%) were e-cigarette users. The prevalence of e-cigarette use was inversely related to age. A significant portion were uninsured (10.7% vs 5.9% of non-users), and almost half (49.9%) were current tobacco smokers. E-cigarette users were as likely to undergo CRC screening compared to non-users [OR 1.40; 95% CI (0.74, 2.66)]. Increasing age, educational level, health insurance, comorbidity, access to a primary care provider, personal history of cancer, and presence of a comorbidity were associated with increased participation in CRC screening. However, e-cigarette use was not associated with increased screening. Our study found no significant difference in CRC screening rates between e-cigarette users and non-users. While screening behaviors appear unaffected for now, ongoing surveillance is important as more users reach screening age given the uncertainties surrounding the long-term effects of e-cigarette use.
